SDI offers courses beginning each month. Semesters are 16 weeks in length with courses of various lengths, typically 8-weeks and 4-weeks, within the semester. The academic week begins at midnight Monday through 11:59 pm Sunday, Mountain Standard Time. Courses are therefore scheduled to begin on Mondays and end on Sundays, regardless of how any holidays fall.
The online classroom is available during holidays. However, the administrative offices will be closed during the holidays listed below. When the holidays fall on the weekend, SDI will typically align with the Federal observance, usually the Friday prior or the Monday following such holiday. Current students will be informed of specific office closures by email and/or website updates.

Just do it! It’s fun! The program is all online so it works with your schedule and you can work on it when you have time. For people who work multiple jobs, like I was, it’s not an issue.Vincenzo Lombardo2018 Associate of Science in Firearms Technology Degree Graduate
